Deploy `findface-facerouter` in FindFace Security¶

To deploy the findface-facerouter component, do the following:

Install findface-facerouter either from the console installer or from the apt repository as such:
```
sudo apt update
sudo apt install -y findface-facerouter
```
Open the /etc/findface-facerouter.py configuration file.
```
sudo vi /etc/findface-facerouter.py
```
If the findface-facerouter and findface-sf-api components are installed on different hosts, uncomment the sfapi_url parameter and specify the findface-sf-api host IP address.
```
sfapi_url                      = 'http://localhost:18411'
```
Open the /etc/findface-security/config.py configuration file. In the ROUTER_URL parameter, actualize the findface-facerouter IP address and port (18820 by default). Specify either external or internal IP address, subject to the network through which findface-video-worker interacts with findface-facerouter.
```
sudo vi /etc/findface-security/config.py

...
FFSECURITY = {
   'ROUTER_URL': 'http://127.0.0.1:18820/v0/frame?',
```
